06 2500 overheating
I"m starting to have issues with my truck overheating. Yesterday was the second time I've had trouble within the last month. I noticed yesterday that the fan did not kick in. Is there a fuse somewhere to look at? I've been searching through some of the previous post about the radiator being clogged with oil. I rather check to see if its a fuse issue before pulling the radiator out.

Our trucks are not like the 2nd Gen crowd. We don't get oil clogged radiators. Trash may but no oil. Most common issue with an 06 for overheating is low on coolant. Pull the radiator cap and take a look. If it is low the most common area for it to leak is on the passenger side of the block, the heater hose connections below the manifold.

Your wrong. the fan clutch is controlled by the ECM. It has a clutch that is applied via a signal from the ECM. Like I said, check the coolant level by taking off the radiator cap. I beat it is low.

FYI, I've noticed that if my AC is on my clutch fan will engage more often especially at slower speeds. To test your clutch fan get your truck up to temp then try turning the AC on/off while driving around town at 30mph or so. That's the speed I can generally hear the fan the most, then hold that speed and turn the compressor off (leave your vents blowing so that noise is constant)... you fan clutch should disengage within a few seconds and get quieter. Then turn the AC back on and your fan noise should come right back.
If you try it a few times and you never hear a difference between AC on/off... then I'd say you might have a clutch fan issue.
However, at HWY speeds even while towing I haven't really ever noticed my clutch fan engaging... Any my last trip out it was 106 degrees outside for 600+ miles, I didn't see anything higher than 220 degrees.

on my '03, I can hear the fan kick on when as the motor approaches 215*. I really only does this when pulling a long grade. With the a/c on, I can hear the fan cycle on and off at low speed, but once over ~35mph, I don't hear it anymore.

I am having a similar problem with my 03. I have a post on it in this same section. I just cant believe it can be the actual fan problem due to the fact it works fine with the A/C on. It seems there must be a sensor/ecm problem
